upon which the clamps of the machine take hold to operate the pens. Withthe ordinary pens the ink is liable to run back along the shank B to theclamps, and along the clamps to the next pen, so that the diii'erentcolored inks become mixed. Toguard against this, I attach a guard orshield, O, to the shank B oi the pens A, so as to prevent thepossibility of the different-colored inks becoming intermingled ormixed. The guard or shield 0 projects upward and rearward, as shown inFig. 1, so as not to interfere with-properly securing and operating thepens.

Having thus described my invention, I claim as new and desire to secureby Letters Patent a The grooved and shanked pen A, provided with shieldC projecting upward and rearward, as and for the purpose described.
